Yes, got it, and that triggered some dubious ideas:  What if we
had a "bytes <nnnn>" clause in the timestamp lines (as an aid
to debug such problems) - in _theory_ it could work, substract
the length of header fields introduced by hop n+1, and then it
should match what hop n reported as length.

Content-Length:  was tried and failed already.  It totally blows chunks
if you hit a gateway that has to do an 8bit->7bit conversion or other
rewriting (there's still the occasional %-hack usage, or just canonifying
to a FQDN in a From:/To:/cc:/whatever:).

(Yes, I know Content-Length: was mostly a MTA-MUA thing on the same system.
If it didn't work there, the idea was doomed for end-to-end...)
